FL-1146 Handle errors logs for building errors

Context

BuildTask on copied from the Celery compute tasks, so the log handler expect a compute task key (which does not exist when building the docker image for a function).

We want to generalize the log error handler to switch from compute task specific, to key + asset_type specific.

We want to rewrite the on_failure function for build_image and save_image.

Specification

Rewrite the store_failure function:

substra-backend/backend/substrapp/utils/errors.py

Line 11 in ba0e33c

def store_failure(exc: Exception, compute_task_key: str) -> Optional[models.ComputeTaskFailureReport]:

to generalize it from compute_task_key to asset_ket, asset_type.

Update the on_failre method for build image celery task and save image celery task

Acceptance criteria

Logs are accessible for build and save image tasks.
